Re: [lifewithoutanet] Object Avoidance Drills
Along the lines of Adam's thoughts:
If you are facing a solid object, and the wind is pushing you into it (which ought to be very rare, since with a headwind, you shouldn't be exiting a solid object), it's often better to turn on toggles.
The reason for this is the total distance the canopy travels toward the object.
Under "ordinary" (i.e. not a headwind blowing you back into a solid object) circumstances, distance travelled toward the object is minimized by using the risers. While this may seem to result in a "slow" turn, the turn while "slower" in time used (it takes more seconds to turn), is actually "faster" in horizontal distance consumed (you move less feet toward the wall).
However, if you add in a headwind, you find that the wind speed gets added to the canopies speed, over time. So, in that situation, you want to minimize the _time_ you spend turning (because you are getting blown toward the object during the turn). So, in the headwind case, you need to minimize turn time in order to minimize horizontal distance used. Which means, often, that you ought to be turning on the toggles.
This is, in my opinion, perhaps the only situation in which an imminent object strike is best addressed with the toggles, rather than the risers. These situations most often occur on slider up cliff jumps (where people are willing to exit into a headwind because they can create more object separation during the freefall).
Note that my use of the term "imminent object strike" pretty much means that you find your body tensing up to accept the impact. If you're 100 feet away from the object (or in any other situation where impact is not imminent) you're usually better off turning on the toggles, because a toggle turn uses less vertical altitude (and in almost every situation not involving imminent impact, vertical altitude is your most precious commodity).
I find it often helps to evaluate a jump by deciding what the "most precious" thing I have at opening is: often it's separation from the wall, but sometimes it can also be time before striking the wall (in a headwind scenario) or altitude before striking the ground. In fact, at different times during the same jump, it will be different things. Choose your turn strategy to conserve your "most precious" commodity, and expend a different one, instead.
